MISSOURI WALL-PAPER REMOVER Application filed April 2,

This invention relates to devices for use in removing wall paper'from walls, and is of the same general character as the device disclosed, for example, in United States Letters Patent No. 97 5,284, granted November 8, 1910, upon application of W. Gr. Roberts et al.

Devices of this character comprise generally a hood that is adapted to rest with its open face in engagement with the wall upon which it is desired to remove the paper, and a heating apparatus for supplying steam to the hood. The hood is generally provided with means tending to prevent the escape of steam 1 between the hood and the wall and in the pat ent referred to the means disclosed-comprises a rubber gasket that is fixedly mounted in the edge of the hood and extends completely around the hood. A feature of the present invention consists in the provision of improved means for use in preventing the escape of steam from the hood, and as illustrated, this means is shown in the form of a.

cylindrical washer or gasket that is restrained normally within a metal holder extending about the periphery of the hood but may be adjusted within the holder to compensate for the Wearing away of the gasket.

Another feature of the invention consists in the provision of a trap or a receptacle combined with the hood for use in entrapping condensation products of the steam. In the illustrated embodiment of the invention the trap comprises a metal trough which extends across the bottom portion of the hood and is open to the interior thereof. During the use of the device the products of condensation are collected in the trough instead of being permitted to run in dirty streaky lines down the wall of the building which it is being operated upon.

Other features and objects of the invention will become apparent from a reading of the following specification in the light of the accompanying drawings, in which:

Fig. 1 is a view in front elevation of a removing hood having associated therewith means for imparting steam to the hood.

Fig. 2 is a view of the open face of the hood of Fig. 1.

1928. Serial No. 266,808.

Fig. 3 is a view taken along the line 33 of Fig. 2, and

Fig. 4 is a view taken along the line 44 of Fig. 2.

Fig. 5 is a view illustrating the means for perforating the wallpaper so as to permit steam to enter beneath said wall paper.

As shown in Fig. 1 a steam generating boiler 10 is provided with circulating tubes 12 and a baiiie 14 for preventing the escape of moisture from the boiler. To the end of heating the water there is provided a fuel tank 16 which feeds a burner 18, and a combustion chamber 20 is located in the path of the flame from the burner 18 and serves in imparting heat directly to the boiler 10. As illustrated the usual equipage of a boiler is provided, as, for example, a pressure indicator 22, a safety valve 24, a Water glass 26, and a valve control led outlet 28. A plurality of conduits 30, 32 extend from the outlet pipe 28 and are adapted to have imposed upon their open ends a flexible tube 34 or a closure plug 36.

The flexible tube 34 serves to conduct steam from the boiler 10 to a wall paper removing device or hood 36 which is formed of a bottom plate 38 and a side wall 40 which extends continuously around the edge of the bottom plate 88 and extends upwardly at right angles thereto. -A central opening 42 in the rear of the bottom plate permits the entry into the hood of steam from the boiler, and to the end of connecting the opening 42 with the flexible tube 34, there is provided a hollow stud 44 and a hollow metal tube 46 surround ed by a member 48 adapted to serve as a handle.

During the use of the device the open face of the hood is placed oppositely to a wall from which it is desired to remove paper, and steam is admitted to the interior of the hood. -Unless some means were employed to prevent such an occurrence the steam would leak out of the hood in which condition articles in the room might be damaged, and accordingly the present invention aims to overcome this danger through the provision of a metal holder or open faced casing 50 which extends completely around the periphery of the hood and contains a hollow rubber tube or gasket 52. As shown in Fig. 4 the outer edge of the gasket extends slightly beyond the open face of the hood, in which position it is the first portion of the device to engage the Wall, and upon so doing flattens out slightly to provide a hermetic seal between the hood and the wall. In the event that the outer face of the rubber tube becomes worn to such an extent that the metal of the .hood comes in contact with the wall, the tube may be removed from the holder, turned over, and reinserted with an unused surface facing outwardly.

It has already been pointed out that the device is provided with means for entrapping the products of condensation, and accordingly as shown in Figs. 2 and 3 the lowermost end of the hood is provided with a small case or receptacle 53 which has an opening therein at 54 for receiving the products of condensation as they fall downwardly from the inside of the hood. The receptacle 53, may of course, be cleaned from time to time in order that it will not overflow.

is illustrated, a vertical extending baffle plate 56 made in the form of a narrow strip extends across the open face of the hood and is bowed out at 58, the central portion, whereby it serves as means for distributing the steam to all parts of the hood as it enters through the opening l2.

In the operation of the device, the steam enters between the wall paper and the wall softening the paste and freeing the paper. To assist the steam in entering the space between the paper and the wall the top of the hood may, as shown in Fig. 5, be provided with a plurality of brackets 60 having mounted there-between a needle point roller 62. in using the roller the paper is first punctured by means of the roller being moved back and forth over the paper, and then when the hood is placed against the perforated paper and steam is introduced into the hood, the pe forations provide passageways for the steam and permit it to enter readily the desired space.

Having thus described the invention what we claim as new and desire to secure by Let- 'ters Patent of the United States, is:

1. A wall paper removing device comprising, a hood, means for admitting steam to the hood, a metal trough extending completely about the periphery of the hood, and a deformable and reversible gasket seated within the trough for use in preventing the escape of steam from the hood.

2. In a device for use in removing wall paper, a hood comprising a bottom plate and a peripheral wall extending at right angles to the bottom plate, and means for admitting steam to the hood, a hollow metal trough eX- tending completely around the hood within the peripheral wall thereof, and a deformable of the hood for entrapping the products of condensation of the steam, said chamber being entirely enclosed except for an aperture which places same n communlcation with the nite 101 of the hood.

4-. A wall paper removing device comprismg, a hood, means for admitting steam to the hood, a gasket associated with the hood for use in preventing the escape of steam therefrom, and a chamber formed at the bottom of the hood for entrapping the products of condensation of the steam, saidchamber being entirely enclosed except for an aperture which places same in communication with the interior ofthe hood.

A wall paper removing device comprising a hood, means for admitting steam to the hood, a bowed ballle located in the path of admission of the steam for distributthe steam to all parts of the hood, a deiormable and reversible gasket associated with the'hood for use in preventing the escape steam therefrom, and a chamber formed at the bottom of the hood for entrapping the products of condensation of the steam. I

6. A wall paper removing device having, in combination, a hood, a deformable rubber gasket Xtending around the periphery of'the hood and means for admitting steam to the interior of the hood, said means comprising a flexible tube and a rigid hollow member in communication with the tube and also-with the hood and adapted to serve as a handle during the use of the device. I

. 7 A wall paper removing device having, in combination, a hood, means for admitting steam to the'interior .of the hood, and a member extending across the top of the hood having sharp projections thereon for perforating the wall paper to permit the passage therethrough of steam admitted to the hood. 7 r

In testinmn that we claim the foregoing we hereunto aliix our signatures.
